OK…this one is a bit tricky. OK, now a 4-year-old boy w/ fever, headache and neck pain. The father states he is not the birth father, and that he and his wife was given the baby during a trip to a third world country. They never gave the boy any shots. Now, he has a fever. There is photophobia, and mildly injected conjunctiva are appreciated. Pupils are equal and reactive and funduscopic examination is unremarkable. The patient has neck stiffness with a positive Kernig's sign (Big hint: What does this mean?). WBC count is over 25 thousand, with 64 segmented neutrophils and 25 bands. A lumbar puncture is performed that reveals elevated CSF pressure, decreased glucose, and elevated protein. A Gram's stain shows gram-negative pleomorphic rods. Growth on chocolate agar reveals white colonies. OK, what is the bug? Does this bug have a capsule? 1-Neisseria meningitidis 2-Streptococcus pneumoniae 3-Haemophilus influenzae Type B 4-Haemophilus ducreyi 5-Klebsiella pneumoniae 6-Group B Streptococcus 7-Listeria monocytogenes 8-E. coli 9-Varicella zoster virus 10-Rhinovirus 11-Measles virus 12-Rubella virus
